Most of the dragons, with whom I spoke, nearly all somehow know how to purr.
I myself too, it turns out, though not as much as I want, so I'm still working on it.
And about "moorchalka" I remembered the picture on the structure of the dragon, there were still "tiskalki", "bodalki"and "dumalka" ...
I decided now is the wall paint and hang. Moorchalka on her chest, you can wear it or swallow it.
The inscription on the poster: "You put yourself moorchalka?"
